That "Init-only properties" feature is huge.

I spend so long at work when working on tests making stubs of objects with private setters etc (e.g. DTOs). That work is essentially gone now, awesome!

It also drove me mad with JSON deserialization. Hopefully this will work nicely with newtonsoft.

I think they said it was only a compiler error, it's still a normal setter underneath, so newtonsoft would not see any difference.

Newtonsoft (and the new Microsoft .NET framework JSON (de)serializer) only uses the setters once too to set the properties after processing the JSON, I can't see it causing an issue.

Are you me? That's exactly the same reason why this feature has me so excited. Will save me so much time when testing.
